The invention relates to mop wringers. The purpose of the invention `isto provide means adapted to be attached to a bucket or other receptaclefor wringing the water fromV the mop.

The invention comprises a cylindrical shell top 'of shell 7 and given atwisting motion having a corrugated wall in helical formation and adownwardly flaring member therein causing a compression of the mop asthe same l0 is twisted into the shell.

Referring to the drawings, which illustrate merely by way of example asuitable embodiment of the invention Fig. 1 is a `plan view of the mopwringer attached to an ordinary bucket.

Fig. 2 is a vertical section on line'2, 2 of Fig. 1. t

Fig. 3 is a sectional detail on an enlarged scale.

Similar numerals refer to similar parts throughout the several views.

The invention comprises the cylindrical shell 7 t having a corrugatedwall 8, the grooves or channels being in the form of a helix. This shellis shown as slightly tapering from the open top to the closed bottomalthough the taper is not believed to be essential. Within the shell 7is positioned the tubular formation 9 having its axis correspending tothat of the shell. This tubular formation 9 has a flaring development atthe bottom, as at 10, with itslower edge or margin joining the bottommargin of the shell 7, as at 11, thus closing the shell at the bottom.This tubular formation 9 extends slightly above the top of the shell 7and is closed at the top. This formationis provided with a number ofholes 1 2 for the passage of water therethrough.

The shell is provided upon or near its upper margin with any suitablemeans, such as the hook 13, for engagement with the top rim 14, of abucket 15 or other suitable receptacle. At the diametrically oppositeside of the shell margin or rim from the hook 13, is provided anothersupporting means such as the bar k16 secured to the shell 7 at about themiddle part thereof and having, at each end, means for engaging theopposite sides of the top rim 14 of the receptacle 15. Inv order thatthe device Amay be attachedv to different sizedv re.-

ceptacles,fthefbar 16 is tubular at each end 'and provided with hookelements 17 slidable therein, having the springs 18 forpullin'g thehooks tightly against the said rim 14. In operation the mop is insertedinto the within the shell to causey it to follow the helicalcorrugations downwardly. This naturally crowds the mop into a graduallydecreasing space, due primarily to the flaring shape of the centralformation 9. This crowding is of course increased by providing adownwardly tapering shell. As the mop 1s crowded into smaller space itis of course i put under pressure to expel the water there# from, whichwaterpasses through the ports or holes 12 into the bucket or receptacle15.

After thewater has been squeezed from the mop a reverse twist is giventhereto and the mop is readily withdrawn from the shell 7.

What I claim is 1. A'mop wringer, comprising a hollow, substantiallycylindrical formation having t its inner wall formedwith a helicalchannel, a body centrally positioned within the cylinder flaring towardthe bottom so that the space between the central body and thesurrounding cylindrical wall decreases from the top toward the bottom. L

2. A mop wringer, comprising a hollow, substantially cylindricalformation having its inner wall formed with a helical channel, a bodycentrally positioned within the cylinder flaring toward the bottom sothat the space between the central body-and the surrounding cylindricalwall decreases from the top toward the bottom, said central bodyprovided with suitably arranged ports for the escape of water.

3. A mop wringer comprising ay hollow, substantially cylindricalformation having its inner wall formed with a helical channel, a bodycentrally positioned within the cylinder flaring toward the bottom sothat the space between the central body and the surrounding cylindricalwall decreases from the top toward the bottom, said central bodyprovided with suitably arranged ports for the escape of Water and meansfor disengageably securing the device to a receptacle.
